⭐⭐⭐⭐⭐ I highly recommend JAS III HVAC, LLC! Mr. Sam was excellent—he quickly diagnosed the issue, explained everything clearly, and completed the work in no time. They installed my furnace two years ago, and I’ve had zero issues since. Anytime I’ve needed help, one call was all it took. Professional, reliable, and trustworthy service every time.

Electric Furnace or Forced Air Heating System Repair Service
The most conscientious and honest contractors I have ever worked with. Not only are they reasonable but if they can’t fix it they will consult with whoever or whatever they need to get it done. The only problem is they don’t have more workers because they are just that good. I will wait on them before I call someone else.

We felt very comfortable in going forward.

Mr. Byrd was very respectful, professional and very efficient. He diagnosed the problems that I was having and proceeded to replace the failed parts and repair the system. My system is some 30 years old, but thanks to him, it runs like new...very efficiently. I highly recommend his company, and in fact, I've reached out him for repair/replacement of my water heater. Being a professional myself, I'm not easily impressed, but I am thoroughly impressed with Mr. Byrd.

All around amazing! Very polite, very prompt, very professional! When my water heater went out, I called we set up a time for them the come out. They were on time and got the service done fast. My son's were very interested in what Mr. Byrd was doing and and he took the time to explain step by step what he was doing and why. Even allowed them to help him. He insisted they weren't a bother to him at all. He also changed some lightbulbs for me that I couldn't reach and got a broken key out of my door lock, free of charge! I will be calling him for everything!! Such a wonderful man and a wonderful experience!
